SEPARATOR FOR SPINNING AND TWISTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 539,613, dated May 21,1895. Application filed October 15, 1894. Serial N0- 5 25,939 (Nomodel.)

To aZZ whom it may concern:

Be it known that I, GEORGE 0. DRAPER, of Hopedale, county of Worcester,State of Massachusetts, have invented an Improvement in Separators forSpinning and Twisting Machines, of which the following description, inconnection with the accompanying drawings, is a specificatiomlikeletters on the drawings representing like parts.

It is often found difficult, if not impossible, to adapt modern wideblades toold spinning machines, for the reason that there isnotsufficient room in which the blades can move. I have aimed to produce awide separator blade which may be readily applied to the ring rail ofany usual form of machine, without in any way limiting the action of themachine.

In accordance with my invention, I mount upon the ring rail, andpreferably clamp to the edges thereof, a series of stands to support thebar to which the separators are attached, and to turn the said bar withits attached separators as the ring rail rises, and bring the separatorsinto the proper position as the ring rail descends, I connect theseparators by a chain or flexible connection with a part of the frame,as will be hereinafter described. By or through the strain of the chainupon the separators as the ring rail descends, the said separators aremade to take their positions of greatest efficiency when the ring railis at the lower end of its traverse, and as the ring rail rises thechain or flexible connection permits the separators to readily turnforwardlyand rest upon the ring rail be tween adjacent rings.

A set of separator blades adds considerably to the Weight to be liftedby the builder mo tion. I therefore prefer to substitute in old frames anew rail composed of sheet metal, flanged at its front and rear edges,the stands sustaining the bar for the separator being made in two parts,so as to be readily clamped upon said edges.

Figure 1, in front elevation, shows a sufficient portion of a ringspinning or twisting machine with my improvements added to enable myinvention to be understood, part of two of the spindles and the front ofthe ringrail being broken out to better show the sepa rator-bar and itssupports; and Fig. 2 shows a section of the frame represented in Fig. 1,the line of section beingindicated by dotted line no.

The frame A, the guide-board A, the spindle rail A and spindles A areand may be all as usual in spinning and twisting frames.

Herein I have shown the ring rail B as composed of sheet metal, itsfront and rear edges being flanged to stiffen the same, said ring railhaving mounted upon it a series of suitable rings 13, upon Which,inpractice,will run any usual traveler. Not shown. Upon the inner edge ofthe rail I have clamped by set screws a a series of stands a, saidscrews entering suitable nuts or blocks a Each stand is slotted ornotched to receive an ear b of a block b pivoted to' the stand by asuitable pivot 2, said block being of suitable shape to receive and holda bar b upon which are mounted a series of broad metallic separators a.One or more of these separators are engaged or surrounded by a loop orring d at one end of a suitable flexible connection 01', preferably madeas a chain, suspended at its upper end by an eye-bolt d or otherwise,the point of suspension being above the highest working position of thering rail. The ring rail may be raised andlowered in usual manner.

The dotted lines in Fig. 2 show the ring rail in its highest position,and the full lines show it in its lowest position.

When the ring nail is down or in its lowest position, the chain orflexible connection d holds the separator 0 up in its highest positionof efficiency, and at such time the center of gravity of the separatoris in front of the pivot 2 uniting the ear with the stand 'a referredto. Now, as the spindle ascends, the separators, by the action ofgravity, gradually tip forward-until they meet the rail between adjacentrings, and by the time that the ring rail reaches its highest position,said separators assume the position represented by dotted lines, thechains or flexible connections in no way interfering with such movement,the loop or ring 61 at such time sliding freely on a part of theseparator.

When the ring rail is down, and the bobbins are sufficiently full to bedoffed from the spindles, the operator needs only to push against aseparator and turn the same back- ICO wardly, as represented in Fig. 2,and as soon as the center of gravity of the separator passes the saidpivot 2, the said separator, together with all those connected to thebar 17 will assume the dotted line position Fig. 2.

Having .described my invention, what I claim, and desire to secure byLetters. Patent,

1. The combination with a ring rail, a bar pivotally mounted thereon,and a series of separator blades carried thereby, of a flexibleconnection having one end supported above the highest position occupiedby the ring rail and connected at its other end to a separator, thelength of the said connection being so proportioned with relation to thevertical movements of the ring rail as to arrest and turn the free endof the separator upwardly about its pivotal point as the ring raildescends, substantially as described.

2. A ring-rail provided with stands, a separator-carrying-bar mountedthereon, and a series of separators attached to said bar, combined witha chain or flexible connection attached to said separators at one endand supported above the highest position occupied by the ring rail,whereby the separators are raised as the ring-rail is lowered, substaitially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE 0. DRAPER.
